AFR-S Arc Flash Protection System

AFR-S arc flash protection system is a cost-effective solution that reduces arc-fault damage in low-voltage (LV) or medium-voltage (MV) feeder loops. Three remote ultraviolet optical sensors can be connected to one device, and can automatically detect the light from an arc flash and rapidly tripping.

This arc flash protection system is used to limit damages to equipment, improve safety, avoid and protect personnel injuries. It can be used as a stand-alone arc protection relay or applied in more complex switchgear layouts.
